After attending a workshop on building MCP servers for #ElixirLang apps, I was really hyped, and I built this!
Now Claude can access Rocket Validator accessibility reports and also run new reports and rechecks. It's mind-blowing. 🤯

Now in public beta, we have an official MCP that you can use to connect your accessibility validation reports to Claude and ask it to run reports, recheck, summarise issues, get a how-to-fix guide... whatever you can imagine

I beta tested this and it’s amazing.
I asked Claude Code: find all html and accessibility errors of YouCongress via Rocket Validator’s MCP tool and fix them.
After a few runs, all green. ✅

Cloudflare's optimized image delivery is nice but for a project I'd like to deliver the images in the original format (PNG, JPEG or WEBP), instead of having it converted to another format.
What would you use as an image CDN so I can deliver the original image instead of an optimized one?

I'm considering buying an e-ink monitor to reduce eye strain, has anyone tried an external e-ink display? Are they good for coding? Grayscale might be enough.

France announced today it’s phasing out Teams, Zoom, etc. to be replaced with a French/European solution called Visio. The data is hosted on Outscale. Transcripts and subtitles are also handled by French providers. The target is set on 2027 for government agencies.
